Rechecked power to the fuel pump using new improved homemade test lamp. (Note to everyone: Be sure to test the test apparatus)
WooHoo! Indeed power DOES flow to the fuel pump when car is cranked.
This, in conjunction with aforementioned fuel-pump-NOT-making-pumping-noises-when-directly-powered observation leads me to believe that I need to repair or replace the fuel pump.
Yes, I've got a good fuel pump in another E30 that I can swap out. But I don't want to dick around with that one if my suspect fuel pump is definately bad. Eventually, I need all the cars to run don't you know.
What comments does anyone have regarding removal/repair/replacement of the fuel pump. Easy? Intuitive? Remove one and replace with another?
Is there some repair kludge to 'free up' the pump?
